IMPROVEMENT IN THE MEANS 0F USING HYDROCARBON OIL AS FUEL.

Specification forming part of Letters Patent No. 39,9 l S, dated September 15, 1863.

To all whom t may concern:

Be it known that I, G. B. HILL, of the city, county, and State of New York, have invented a new and useful Improvement in the Application of Hydrocarbon Liquids as Fuel; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in Which- Figure l represents a transverse vertical section of my invention. Fig. 2 is a horizontal section of the same.

Similar letters of reference indicate corresponding parts in both views.

The object of this invention is to apply hydrocarbon liquids, and particularly petroleum, in a crude or refined state, as fuel in furnaces, stoves, and so forth.

The invention consists in the employment or use as fuel in steam-boilers and other furnaces, and in stoves, and wherever it may be applied, of a mixture of steam with petroleum or other hydrocarbons in such amanner that by the blaze of this heating-mixture the steam-boiler, stove, or other article can be heated to a very high temperature in a short time and with great economy in fuel. rlhe petroleum or other hydrocarbon liquid is vaporized by the same name which heats the boiler, andthe pipes which conduct the steam and l1ydrocarbon-vapor to the mixer are conducted over the flame of the burner, so that the same are partially superheated.

To enable others skilled in the art to make and use my invention, l will proceed to describe it.

A represents the trebox of a locomotive or other steam-boiler, constructed in the ordinary manner. The grate from this fire-box is replaced by a s) stem of pipes, B, which radiate from a center piece, C'. This center piece consists of two cylindrical vessels, a a. of different diameters, the largest vessel a being placed on the top of the smallest, and from the lower cylinder, a', the pipes B radiate, as clearly shown in Fig. l of the drawings. The drum a, or the mixer, communicates, by` means of a pipe, b, with a tank, D, containing petroleum or other hydrocarbon liquid,

and a pipe, bf, leads from said mixer to a supplementary boiler, E. The radiating-pipes B are perforated with a number of holes, c, and these holes may be provided with burners c or used without such burners. The inner holes or burners are situated under the mixer, so that the contents of the same are heated, and the pipes I) b pass over the flame from said burners.

In starting the fire steam is raised in the supplementary boiler E. and by. opening the stop-cocks in the pipes b b steam and hydrocarbon liquid are admitted to the mixer a. rlhe hydrocarbon liquid, on coming in contact with the steam, is vaporized, and the mixture of vapor and steam as it emanates from the burners, can loe ignited. The flame of the burners strikes the mixer and also the pipes b b', and the vaporization of the hydrocarbon liquid is thereby facilitated, and the steam, passing through the pipe b', is superheated, so that when the vapor and steam arrive in the mixer they will combine readily, 'and a compound will be formed, which, in reaching the burners, will burn with a bright blaze. After steam has once been raised in the main boiler the use of the supplementary boiler can be discontinued and steam from the main boiler used to supply the mixer.

This invention has been successfully applied to a locomotive-boiler, and it is found that lthe steam can be raised to and maintained at the desired pressure with a very small expenditure of hydrocarbon liquid. My inven- G. B. HILL.
